your motor will be a 292 and the trans if a 3 speed will be a th350 if it has a cable kick down on the caarb linkage ..a th400 has an electric kick down and no cable ..also a 350 oil pan looks square with the right rear corner cut off while a th400 isnt square ,rectangle or round ..its got bulges all over the place and not likely in your truck..
